A client intake calculation: The client received one 100 mL intravenous antibiotic, one eight-ounce cup of ice chips, one eight-ounce cup of coffee, one eight-ounce cup of ice cream, and three eight-ounce cups of water. What is the total intake in milliliters?

• A. 1300 mL
• B. 1420 mL
• C. 1500 mL
• D. 1600 mL

Answer: (B)

Converting all intake items to milliliters and applying the standard half-volume rule for ice chips is the key. Assume 1 cup equals 240 mL. The intravenous fluid is 100 mL. Ice chips: an 8-ounce cup is 240 mL, but ice chips count as half the volume, so 120 mL. Coffee: 8 ounces equals 240 mL. Ice cream: 8 ounces equals 240 mL. Water: three 8-ounce cups equal 3 × 240 = 720 mL. Add them up: 100 + 120 + 240 + 240 + 720 = 1420 mL.
